Which road bike helmet

Fox Dropframe Pro. The correct size helmet will sit low and straight on your forehead. The right helmet will fit comfortably on your head, and the retention system will easily snug up the fit.

Trevor Raab. Specialized competitivecyclist. ANGi crash sensor. Very pricey. Giro competitivecyclist. Fits heads as small as 45 centimeters in circumference Very lightweight. Dropframe Pro. Fox Racing competitivecyclist.

Lots of protection. Fixed Visor. Roam MIPS. MET competitivecyclist. Comfortable Great ventilation. Visor looks big but doesn't provide great coverage. Look and feel of a high-end road helmet degree size adjustment system helps with comfort. Ventilation isn't quite as good as pricier options. Helios Spherical. Shell-in-shell construction is comfortable and offers great protection. Still not a cheap helmet. Lumos Ultra. Three LED lights provide full visibility Remote activated turn signals. One size fits most sizing Not certified for e-bike use.

G1 MIPS. Lazer competitivecyclist. Smith rei. Koroyd material offers protection similar to Wavecel. Can feel hot in the summer. Comes with ANGi crash sensor. Vents are on the small side. Has dial-adjust fit system and removable visor. Reducing the rotational forces means the risk of brain injuries is minimized. Take a look at the following picture of the strain level for illustration. This means MIPS helmets are one of the best road bike helmets for your safety.

MIPS allows the head to move mm inside the helmet. This reduces harmful rotational motion that would otherwise be transferred to your brain and cause injuries. The movement is possible thanks to the inside construction.

Watch the following video to learn more. What is the MIPS downside? The main downside of bike helmets with MIPS is the weight. These helmets are heavier for about 0. MIPS also does not reduce linear forces. There are some differences though. The following animation illustrates it well. WaveCell is a cellular structure inside of a helmet that reduces impacts and rotational forces.

It is used by Bontrager helmets. Trek explains the WaveCell technology in 3 steps:. What is the WaveCell downside? You can learn more about bike helmets in my in-depth guide on How to choose a bike helmet.

There are three main reasons to replace a bike helmet: 1. After a crash If you crash on your bike and the helmet will get in touch with the ground — make sure you replace it. The damage done to the helmet may not be visible, but it can be cracked inside. This crack may cause a disaster. If you crash with the same helmet again, it may not protect your head, and you can experience severe injury. Your health is one of the most important things you have.

Your helmet is too old Research and development are fast — the materials get lighter, stiffer, and provide you with better protection.

Yet, these improvements are not as quick as they were before. But the improvement of safety is not as massive. This means that if you buy a helmet from , you will get the same protection as with a helmet from So, when your helmet gets old?

Well, that is a tricky question. There are no studies that would prove the aging of your helmet. If you can afford to spend some money, five years is a good cycle for replacing your helmet. You will take advantage of new technologies and improvements that manufacturers came with throughout the years.

You want an upgrade The last reason to replace a helmet is an upgrade. You can upgrade whenever you have some money to spend, and there is a new model that grabs your attention.

If you can, feel free to upgrade whenever you think it is the right time. I believe you will take advantage of this selection of the best road bike helmets. You may be surprised, but cheap helmets are usually as safe as expensive bike helmets. Why are the premium helmets so expensive? The manufacturers also invest heavily in marketing and sponsorship.

Naturally, this increases the price of the final product. Yes, it is. It is good to point out that this study was lead by people who developed WaveCell and co-founders of Legacy Research Institute, Dr. Michael Bottlang, and Dr. Steve Madey. So, the results may be biased. As a bonus, I did an overview of helmets that the World Tour teams wore on the Tour de France and in the rest of the season:.

Bike helmet parts Product picture credit: Rockbros. The helmet of this racer fits properly. The weight saving over most other helmets will have a negligible effect on your speed, obviously, but you might find it more comfortable than one that's even 50g heavier. I barely noticed it in use. How come? It's down to the elastic modulus of the carbon cage that's embedded into it, says Met. You can see the black woven carbon beneath the white in-moulded polycarbonate shell. Met insists that this carbon is structural rather than cosmetic.

It's lightweight and comfortable and we've found that most people get on with the fit there are always exceptions so try before you buy. Plus, if you accept Met's figures, it offers an aero advantage. The only real sticking point is the price. The Giro Helios Spherical helmet benefits from the trickling down of the company's highly praised MIPS Spherical technology — which was first introduced on its top-end Aether — to this less race-focused lid.

It's comfortable, well ventilated and lightweight enough. It's pretty light and ventilation is excellent, though it's not cheap. It looks closer to the kind of thing you'd have seen Eddy Merckx wearing in the 70s than the sort Chris Froome wears today. One of its big benefits is excellent ventilation. Throughout the test rides I could feel a stream of air blowing across the top of my head, removing excess heat perfectly. It is a high-end helmet with great tech specs, good looks and plenty of choice in terms of design.

Ventilation is superb and it's also lightweight. The price is high, but there are others out there that cost more. Read our review of the Ekoi Legende. A cycling helmet comprises a thick layer that provides shock absorption, with soft cushioning for comfort where it rests on the head. The main shock-absorbing layer is almost always made from polystyrene foam, though there have been attempts to use polyurethane foam and treated cardboard.

Between the green and black sections of co-moulded outer shell you can see the shock-absorbing polystyrene. A thin plastic shell covers the foam to protect it from everyday nicks and scrapes. This shell is usually 'co-moulded' or 'in-moulded', that is, the outer shell is placed in the mould and then the polystyrene layer is formed into it.

A few helmets still have thicker hard plastic shells, which provide some shock absorption in addition to the polystyrene layer, but add weight. The shock-absorbing layer and shell are held on the head with straps, usually made from some sort of synthetic fabric webbing and closed with a buckle.

There's almost always an additional cradle at the back of the head to stabilise the helmet by grabbing the occipital protuberance near the base of your skull. Big vents in modern helmets help keep your head cool. Since polystyrene foam is an insulator, helmets need ventilation to stop the rider's head from overheating.

Early helmets simply had holes in the shell. Modern designs use channels inside the shell that allow air to flow over the rider's head. Many helmets have dial adjusters to tweak the fit. For a helmet to stay in place and be comfortable, it must be adjusted to fit the wearer's head.

Most helmets have some sort of mechanism to adjust the fit on the occipital cradle at the rear of the helmet. Internal reinforcement helps high-end helmets meet standards while shedding weight. Some helmets have internal reinforcing skeletons to hold them together in an impact. This allows for larger vents and air channels, and usually a lighter helmet, but the complication of including extra components in the moulding makes such helmets more expensive. In the UK and the European Union, helmets must meet the EN standard, which calls for a deceleration of no more that g to be transmitted to the head in an impact at 5.

The standard involves impacts on a flat surface and a kerbstone. The two are roughly equivalent in terms of impact absorption. A MIPS helmet is claimed to offer additional protection against rotational forces in a crash, by allowing two layers of the helmet to move independently. The idea is that the outer layer moves when you hit your head, absorbing the rotational forces of the impact. Riders prefer lighter helmets for obvious reasons.

The lightest helmet we've ever tested was the g Specialized Prevail S-Works ; the heaviest was the Abus Performance at g. A peak helps keep the sun out of your eyes or the rain off your glasses.

Helmets intended for mountain biking often have a peak or visor, which provides a degree of shade for the rider's eyes. The styling comes from motocross, but peaks are useful on the road too. They provide shade in summer, keep the rain off your glasses in winter and annoy people silly enough to take The Rules seriously. An aero helmet will shave another few seconds off your mile time trial time.

Dedicated time trial specialists use helmets shaped to cut through the air, with smooth shells and long tails. Their shape has earned these helmets the nickname 'sperm hats'. They're effective if the tail is near the rider's back, but some find the effort of maintaining the right position fatiguing. Helmets with shorter, rounded tails provide most of the benefits without causing aerodynamic problems if you look down. Giro's Air Attack was one of the first 'aero road' helmets with fewer vents for better aerodynamics.

A recent trend is for helmets with minimal ventilation and smooth outer shells to reduce air resistance for general road racing. Is this on right? Helmets for toddlers carried in child seats often have little or no ventilation so they help keep junior's head warm. For older kids, helmet design is very similar to lids for adults, with the exception that they have buckles that release if the helmet gets caught on something so the straps don't throttle the child.

If you like road. As a subscriber you can read road. Adjustable and comfortable straps are also incredibly important — you need to be able to wear them with a fairly snug fit against your chin for maximum effectiveness.

Most cycle helmets are primarily from expanded polystyrene EPS foam. This skeleton is then covered, to varying degrees, in a hard polycarbonate shell and sometimes a dash of carbon fibre to add strength and protect the EPS foam from accidental bumps and scratches.

Naturally, manufacturers claim these designs offer benefits over traditional cycle helmets, but whether those benefits are realised in real life remains to be seen. Every helmet on this list does just that, if not more, and should at least offer your head some protection against bumps and scratches if you fall off your bike while out riding.

These innovations claim to offer increased protection from head and brain injuries by reducing rotational forces or simply by using materials that are better able to absorb certain shocks.

There is some independent safety testing of cycle helmets , but these things are obviously harder to test outside of the lab, where there are so many variables at play. On balance, these extra safety features are almost certainly worth having, but they tend to come on helmets with a higher price tag. For fast road riding, especially in hot weather, ventilation is key. A well-designed system of vents and channels in the internal structure of a helmet can help to draw air over your head and dissipate heat.

As might be obvious, putting holes in a helmet to increase ventilation is likely to lead to reduced weight and, potentially, robustness. So to make up for that, airy helmets often need more external reinforcement or are constructed with pricier materials, to ensure they still meet safety and durability standards.

The aero brush touches everything these days, increasing costs and making all your current kit feel outdated, but with helmets it probably does make sense. There are compromises of course: increasing aerodynamic efficiency usually means closing off ventilation holes or putting up with funky shaped lids that, frankly, have looks that sometimes border on the ridiculous.

Beauty may be in the eye of the beholder, but it is worth considering what kind of riding the helmets you like the look of are designed for. Simon Bromley is a senior technical writer for BikeRadar.
